Abstract
THE INVENTION PROVIDES PROGRESSIVE ADDITION LENSES IN WHICH LENS UNWANTED ASTIGMATISM IS REDUCED AND CHANNEL WIDTH THROUGH THE INTERMEDIATE AND NEAR VISION ZONES IS INCREASED AS COMPARED TO CONVENTIONAL PROGRESSIVE ADDITION LENSES. THIS RESULT IS ACHIEVED BY COMBINING TWO OR MORE PROGRESSIVE ADDITION SURFACES, WHICH SURFACES IN COMBINATION PROVIDE THE DIOPTRIC ADD POWER OF THE LENS. (FIGURE 3& 4B)
